Mustard gas or sulfur mustard are names commonly used for the organosulfur chemical compound bis(2-chloroethyl) sulfide, which has the chemical structure S(CH 2 CH 2 Cl) 2, as well as other species. In the wider sense, compounds with the substituents −SCH 2 CH 2 X or −N(CH 2 CH 2 X) 2 are known as sulfur mustards or nitrogen mustards ...
The proportion of mustard gas fatalities to total casualties was low; 2% of mustard gas casualties died and many of these succumbed to secondary infections rather than the gas itself. Once it was introduced at the third battle of Ypres, mustard gas produced 90% of all British gas casualties and 14% of battle casualties of any type.
Yellow Cross (Gelbkreuz) is a World War I chemical warfare agent usually based on mustard gas (sulfur mustard, HS, Yperite, Lost). The original Gelbkreuz was a composition of 80–90% of sulfur mustard and 10–20% of tetrachloromethane or chlorobenzene as a solvent which lowered its viscosity and acted as an antifreeze , or, alternatively, 80% ...
The whole affair was kept secret at the time and for many years after the war. According to the U.S. military account, "Sixty-nine deaths were attributed in whole or in part to the mustard gas, most of them American merchant seamen" [102] out of 628 mustard gas military casualties. [103]
The idealized combustion of mustard gas in oxygen produces hydrochloric acid and sulfuric acid, in addition to carbon dioxide and water: (ClC 2 H 4) 2 S + 7 O 2 → 4 CO 2 + 2 H 2 O + 2 HCl + H 2 SO 4. Bis(2-chloroethyl)sulfide reacts with sodium hydroxide, giving divinyl sulfide: (ClC 2 H 4) 2 S + 2 NaOH → (CH 2 =CH) 2 S + 2 H 2 O + 2 NaCl ...
Islamic State militants most likely used mustard gas, a banned chemical weapon, against Kurdish forces in Iraq. Exclusive: Watchdog to probe alleged mustard gas use by Islamic state Skip to main ...
General John Pershing called Woodfill the most outstanding soldier in World War I. [1] During an offensive in October 1918, he single-handedly neutralized three German machine gun emplacements while suffering under the effect of mustard gas, and was able to successfully lead his men safely back to the American lines without casualties.
By the end of the war, poison-gas use had become widespread on both sides. By 1918, a quarter of artillery shells were filled with gas and Britain had produced around 25,400 tons of toxic chemicals. Britain used a range of poison gases, initially chlorine and later phosgene, diphosgene and mustard gas.
